+Hi. I've generated a 2047-bit "strong" prime number that I would like to
+use with Diffie-Hellman key exchange. I assert that not only is this number
+'p' prime, but so is (p-1)/2.
+
+I've used the mpz_probab_prime() function in the Gnu Math Package (GMP) version
+1.3.2 to test this number. This function uses the Miller-Rabin primality test.
+However, to increase my confidence that this number really is a strong prime,
+I'd like to ask others to confirm it with other tests. Here's the number in hex:

+q should be prime, and ideally should be a "strong prime",
+which means it's of the form 2n+1 where n is also prime.
+q also needs to be long enough to prevent the attacks LaMacchia and
+Odlyzko described (some variant on a factoring attack which generates
+a large pile of simultaneous equations and then solves them);
+long enough is about the same size as factoring, so 512 bits may not
+be secure enough for most applications.  (The 192 bits used by
+"secure NFS" was certainly not long enough.)
+
+a should be a generator for q, which means it needs to be
+relatively prime to q-1.   Usually a small prime like 2, 3 or 5 will
+work.

+
+Since your prime is really random, proving it is hard.
+My personal limit on rigorously proved primes is ~350 digits.
+If you really want a proof, we should talk to Francois Morain,
+or the Australian group.
+
+If you want 2 to be a generator (mod P), then you need it
+to be a non-square.  If (P-1)/2 is also prime, then
+non-square == primitive-root for bases << P.
+
+In the case at hand, this means 2 is a generator iff P = 11 (mod 24).
+If you want this, you should restrict your sieve accordingly.
+
+3 is a generator iff P = 5 (mod 12).
+
+5 is a generator iff P = 3 or 7 (mod 10).
+
+2 is perfectly usable as a base even if it's a non-generator, since
+it still covers half the space of possible residues.  And an
+eavesdropper can always determine the low-bit of your exponent for
+a generator anyway.
